With the help of Twitter, celebrities can confirm or deny popular rumors to millions of people with just the click of a button. Over the weekend, Kaley Cuoco did just that to dispel any question that she might be pregnant.

“I would like to make something very clear to anyone who cares,” she tweeted. “IAM NOT EFFING PREGNANT. Do with that what you will.”

The pregnancy rumors likely started because of the actress’ whirlwind engagement to Ryan Sweeting in September. The couple had been dating for less than three months when he unexpectedly popped the question to the Big Bang Theory star.
